A few years ago I was bored in stand and started blowing into my grunt tube. Low and behold I heard something grunt back at me. I waited, nothing...I grunted again, it grunted back. I figured it was another hunter, so I grunted and it grunted back, had to be another hunter. Well I got frustrated and blew very loudly into the tube, the next thing I know I heard my first growl and snort weeze followed by a nice buck chasing a doe through the swamp about 40 yards from me. Didn't think much about it until recently when I seen the Drury's promoting their call...THAT WAS THE SOUND I HEARD. Over30 years hunting, heard it once.
